MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 356,422, dated January18, 1887.

Application filed December 3, 1884, Serial Nal-19,366. (No model.)

To LZ whom, t may concern:

Be it known that I, ROBERT W. PAIN, of New York, in the county and Stateof New York, have invented a certain new and useful Improvement inMechanical Musical Instruments, otwhich the following is aspecilication.

I will describe a mechanical musical instrument embodying myimprovement, and then point ont the various 'features in claims.

In the accompanying drawings, Figure l is a transverse vertical sectionot' a mechanical musical instrument embodying my improvement. Fig. 2 isa plan of a part thereof. Fig. 3 is a perspective view of amellowing-board used therein. Fig. 4 is a longitudinal section of apneumatic motor comprised in it. Fig. 5 is a front view of a rest for atraveling music-sheet, and Fig. 6 is a transverse section of this rest.

Similar letters ot' reference designate corresponding parts in all theligures.

A designates the case of the instrument. It

may be of any suitable construction. B designates oneof a series ofsound-producing devices, consisting of reeds arranged in cells c. Thecells a communicate with a wind-chest, C, under control of valves D. Thewind-chest communicates with an equalizer7 E, with which are combinedbellows E. The bellows F may be of any suitable construction. As hereshown the bellows are suction-bellows. The equalizer E is, as usual, ofbellows-like construction.

The valves D of the reed-cells are arranged in the wind-chest C. Eachvalve consists of a lever, which may be made of wood or analogousmaterial, provided with a face of sheepskin or like substance, c, andfulcrumed near one end toapin, b. It is preferably guided in itsmovements by a pin, d, extending through it. A spring, e, holds itnormally in position to cut off communication between the reed-cell andthe wind-chest. f

motor, G, arranged in line with it in the wind-chest. The pneumaticmotor consists of a strip of wood or like material fastened by aflexible material to the upper wall of the Each valve D extends over apneumatic music-sheet, I, travels over the rest H and 6o .controls thepassage of air to the interior of the motors. These ducts f convergetoward the middle of the rest as they extend upward; hence a music-sheetnarrower than the range of motors can be used.

Vhen air is admittedtoa pneumatic motor, the latter is expanded, and itthen opens the valve D, with which it acts. On the entrance of the air avalve, g, consist-ing of a resilient strip of metal, is closed. Then airis cut off, the valve g opens and the air within the motor passes to thewind-chest. .g

In order to soften and mellow the sound of the reeds, I arrange amellowing-board, B', over the fronts of the reed-cells. Thismellowing-board extends up from the top of the windchest C and over theboard in which the reedcells are formed. The front of this board inwhich the reed-cells are formed is oblique, owing to the fact that thereed-cells are all in line at the rear end, and only as long asisrequisite to enable them to contain the diiierent sizes of reeds whichare used for different notes. I do not, however, make the uprightportion of the mellowing-board parallel with the front of the board inwhich the reed-cells are formed, but parallel with the rest H and frontof the yiustrument-case. I have yfound this productive of the bestresults. An open-A ing, b, preferably located in the upright portion oi'the mellowing-board, emits the sound. On the inellowing-board is anupwardly-extending rib, B2. The case A has a hinged cover, A, which,when shut down, rests upon this rib B2. It also has a hinged cover,-A2,which, when closed, rests against the front of the rib B2. Either coverof the case may be opened and closed at pleasure.

VhzLt Ielaim as my invention7 and desire to 2. The combination of themelloWing-bonrd 1o secure byLettels Patent, is- B, its rib B2, andthecovers A AL of the case,

l. The Combination, with the reed-cells of n substantially as specified.musical instrument ending` at nn oblique line, of n mellowing-bom'dextending in front and over the forward end of the range of reedcellsand parallel with the from; of the ense, and having an opening oppositethe ends of the reed cells, substantially as Specified.
